Abstract: A conductive C-plane GaN substrate has a resistivity of 2×10?2 ?·cm or less or an n-type carrier concentration of 1×1018 cm?3 or more at room temperature. At least one virtual line segment with a length of 40 mm can be drawn at least on one main surface of the substrate. The line segment satisfies at least one of the following conditions (A1) and (B1): (A1) when an XRC of (004) reflection is measured at 1 mm intervals on the line segment, a maximum value of XRC-FWHMs across all measurement points is less than 30 arcsec; and (B1) when an XRC of the (004) reflection is measured at 1 mm intervals on the line segment, a difference between maximum and minimum values of XRC peak angles across all the measurement points is less than 0.2°.

Abstract: A measurement device including a processor, wherein the processor is configured to transmit advertisement information to a communication terminal in advertisement processing for establishing communication between a host device and the communication terminal, the advertisement information including state information indicating a state of the host device and bonding information indicating a presence or an absence of storage of an encryption key used for communication with the communication terminal, and in advertisement processing for re-establishing communication after the encryption key is shared between the host device and the communication terminal, the advertisement information includes bonding information indicating stored of the encryption key and state information indicating a current state of the host device.

Abstract: A measuring apparatus and a measuring method that enable measurement to be performed faster and more accurately in POCT, for example, are provided. The measuring apparatus is provided with a measurement unit for performing measurement processing on a sample, an input unit for inputting data that is associated with the measurement processing by the measurement unit and belongs to one of a plurality of attributes, and a display unit for providing a user with information visually. The display unit displays an individual display pattern having an attribute display portion area for displaying a plurality of attribute display portions that respectively correspond to the plurality of attributes and an input instructing area for visually instructing an operation for inputting the data belonging to the attribute corresponding to one of the plurality of attribute display portions displayed in the attribute display portion area.

Abstract: An information acquisition device 10 includes a data acquisition unit 11 acquiring measurement data from an external measuring device 20; a code reading unit 12 reading a code to acquire the information represented by the code; and a data processing unit 13 that associates the information acquired by the code reading unit 12 with the measurement data acquired by the data acquisition unit 11. Medical measuring devices used to measure patient status can be suggested as the measuring device 20. In such a case, for example, codes representing identifiers that identify patients can be used as the code.
